During San Diego Comic-Con, a select group of lucky "Captain America" fans got to see a special screening of the upcoming short film, "Agent Carter." The new Marvel One-Shot picks up with Agent Peggy Carter right where 2011's "Captain America: The First Avenger" left off, with Hayley Atwell's formidable secret agent joining proto-S.H.I.E.L.D. just after the end of World War II.

As Entertainment Weeklypreviously revealed, the short film also stars Bradley Whitford as the sexist Agent Flynn and Dominic Cooper, who reprises his role as Howard Stark. Now, thanks to the magic of the internet, fans everywhere can watch an action-packed fraction of what those lucky SDCC attendees saw in full.

"Agent Carter" will be released on the "Iron Man 3" Blu-ray on September 24th.
